pcileech over PCIe multiplexer?
I am using a PCIe multiplexer and have potentially the following connected in the multiplexer: the screamer and another PCIe device.
I've confirmed the following:
- if I connect the screamer directly without the multiplexer, pcileech works fine:
# pcileech -device fpga probe -v

if I connect just the other PCIe device on the multiplexer, the other PCIe device works fine
-
if I connect the screamer only in the multiplexer, pcileech does not work:

You'll notice the following:
- the screamer is detected fine
- the memory map is not detected
- all the pages being read are failure
I've tried lots of options to increase the delays, read less data, etc. and they all seem to fail (but happy to test more if you have ideas!)
- if I connect the screamer and the other PCIe device on the multiplexer, the PCIe device works fine, but the screamer does not work (same as 3))
I have tried with PCILeech_files_and_binaries_v4.15.1-linux_x64-20220820 and with PCILeech_files_and_binaries_v4.15.1-linux_x64-20221004 and same behaviour.
I think this would require some research, and that it may also be depending on what kind of adapter you're using.
I have had success with this in the past. Also you seem to get a PCIe ID from the adapter which is good.
Interesting would be if you would be able to read memory at all, with pcileech.exe display -min 0x1000 -v -vv -vvv -device fpga
Probe is really aggressive. I recommend against using it since it may break things. Take it from the display command, or possibly by sending raw PCIe TLPs and try to find out what's going on. It may be that you'd need to supply a "memory map" for this.
I'm really sorry I won't be of much help with this one. To really look into it I'd need to take a look at the actual adapter and sit with it a while... Anyway best wishes with this and please let me know how it goes.
Thank you for your reply, really helpful insights/comments.
At the bottom you'll have the output of all the commands.
- from 1) and 2), it does no look like I cannot read any memory at all, indeed.
- from 1), 2) and 3), it is unclear why the memory map is not taken into account as afaict the verbose output actually shows it in
LcMemMap_AddRangeand it looks legit? A bug in pcileech or am I missing something? - from 4), it seems my
memmap.txtdoes not change anything as pcileech had detected it anyway as shown by the duplicatedLcMemMap_AddRange, right? - if you have pointers to send raw PCIe TLPs and how that would help me debug the problem, that would be helpful.
- if that helps, this is the adapter I am currently using https://www.amazon.co.uk/dp/B097H53Z4P/
- may I ask what multiplexer you successfully used in the past with pcileech?
- I've stripped output when it was all zeros for consistency.
- verbose display from 0x1000
# pcileech display -min 0x1000 -v -vv -vvv -device fpga

It's really hard for me to know what the issue is. You seem to receive an error from upstream (The Cpl packet instead of a CplD packet). You also have the master abort flag set in the status register of the config space which may cause issues if the upstream bridge would care about such things.
I assume you did the test above after a fresh reboot / reconnect and not after you did the probe.
Sometimes the OS will disable "busmaster capabilities" (i.e. DMA) when the computer is locked. Windows 11 sometimes does this as part of its DMA protections. After you login this restriction may be lifted. I don't know if this is your issue though.
I actually hadn't tried the test above after a fresh reboot. So I tried again but it seems the same result. FWIW this is not for a Windows device or similar, it is against an embedded device. I was initially waiting for it to boot, but I've tried to do it earlier at boot below, even if I don't think it matters in my case since when I don't use the PCIe multiplexer and do the DMA attack directly connected, I can do it right after boot or later after it has already booted.
Anyway, the result below is when I plug power for the screamer but I haven't plugged power for the embedded device yet, it seems normal:

Memory Display: Failed reading memory at address: 0x0000000001200000.
Anyway, nothing new afaict and I don't have any more ideas. Thanks any for your pointers.
I really don't know. I see you haven't got a PCIe ID in the 1st log you posted. In the 2nd you got the PCIe ID assigned but you're getting unsupported request completions for your memory read attempts. It seems like DMA is blocked to me. Maybe the OS is actively blocking DMA from rouge devices in your case?
I'm closing this issue since it's not much I can do about it. I would really have to sit with the hardware myself to try to debug this.
I know the PCILeech is working with some PCIe multiplexers though, but it may differ between the different onces.
